checked-no =>Play as Luigi: Once you defeat Bowser in world 6, you'll be able to switch between Mario and Luigi at any time while on Starship Mario - just enter the L (or M) door on the brim of the cap! =>World S: Complete world 6 to unlock World S, the special world. =>Green Stars: Once you gather all 120 stars and beat Bowser in World 6, you'll be notified that Green Stars are now hidden in the levels. There are 120 Green Stars in total - one for each level, just like the original 120. =>Grandmaster Galaxy: Collect all 240 stars and a final Galaxy will appear in World S - the Grandmaster Galaxy. This level features star 241 and the 49th Comet Medal. * Grandmaster Galaxy Perfect Run: Once you've beaten "The Ultimate Test" in the Grandmaster Galaxy, collected the Comet Medal for that level, and have a total of 9,999 Starbits stored with Banktoad, you'll unlock "The Perfect Run" in Grandmaster Galaxy. Finish the Run without getting hit once to get the 242nd star! =>Banktoad Upgrades: As you give the Banktoad more and more starbits, he'll change his outfits. * 1000 - Glasses * 2000 - Spear & Shield * 4000 - Pickaxe * 6000 - Diving outfit * 8000 - Explorer's outfit * 9999 - Unlock the Grandmaster Galaxy's "Perfect Run" level. =>Watermelons: Once you've collected/banked 9999 Starbits, all coconuts will change into watermelons. There aren't many levels with these, though. =>Death Count: Complete The Perfect Run and your save file will display your total number of deaths. =>Infinite Lives: Enter the Supermassive Galaxy in world 4 and play until you reach the three giant Koopa Troopas walking around a circular level. Use CNTRL II to freeze a Koopa Troopa (hold A while the cursor is on it) and while it is frozen, have Mario hop on top of the Koopa. He'll keep bouncing up and down, and you'll start earning extra lives. =>Luigi Ghosts: If you complete a level using Luigi, you'll unlock a special Luigi "ghost" for that level. Replay the level and you'll see a ghostly Luigi running through the stage, sometimes pointing out hidden objects, sometimes simply acting oddly. If you'd like to unlock ALL the hidden Luigi ghosts without playing the levels as Luigi, collect a total of 9,999 coins. =>Floating Yoshi Glitch: It's possible to endlessly flutter jump while riding Yoshi, although it's not that easy. While riding Yoshi, hold A to jump and KEEP HOLDING IT. Before Yoshi finishes his flutter/kicking, press Z, release A, and quickly hold A again. You can repeat this sequence to continually float, climb, and flutter.
